Disruptive banking with basic income

Been pondering UBI and cryptocurrencies etc and, I’ve got stuck on this idea that - the most bulletproof way to deliver it would be for the blockchain mining element to tick over as part of a normal bank account. The blow to economy could be contained by making them spendable on education and health only, maybe by a voluntary donation to social health/education.

It’s a half formed thought at best, but by tying it into a normal banking system and making it socially equitable it;s not directly competing (to begin with) in the capital economy.

I have no idea if that makes sense but it’s out of my head now!
